Abra River

The Abra River, also called Lagben River, is the seventh largest river system in the Philippines in terms of watershed size. It has an estimated drainage area of 5,125 square kilometres (1, 979 sq mi) and a length of 179 kilometres (111 mi) from its source near Mount Data in Benguet province.

In 1823, an Augustinian priest, Fr. Bernardo Lago arrived on the town of Pidigan, where he built a church and a rectory atop a hill near the river, marking the official start of Catholicism in Abra. In 2022, the Abra River Fault, which runs along the river, triggered a magnitude 7.0 earthquake in Abra.

The Abra originates in the southern section of Mount Data. It descends westward to Cervantes, Ilocos Sur, and flows into Abra. At a point near the municipality of Dolores, it is joined by the Tineg River, which originates in the uplands of Abra. There are also other small rivers like the Binongan River, Ikmin River, and other rivers connecting to Abra River.
